The tactical Amanita signals achieved a cumulative gain of +50.9% from 3/31/09 (beginning) through 12/31/10. Profits were totaling +72.7%, losses -21.8%, resulting in an excellent profit/loss-ratio of 3.34 to 1. The Amanita performance is even better than at first look:

no leverages in the Amanita performance calculation: In reality one is working with leverages, so practical performance is much higher.

mostly tax-free because of focus on physical metals: In the US and many other countries capital gains are taxed heavily (often around 25%), only physical precious metals are tax-free in all (?) countries around the globe.

technical reasons: When an asset class is gaining a lot, its share in percentage terms is rising - unless one is re-balancing the portfolio every day, which almost never happens in reality. Thus the constant share assumed in the portfolio (e.g. 15% silver) makes the official performance artificially low.

low number of transactions: The comparably low number of transactions consumes little time. Certainly there are very profitable intraday trading systems, but they steal your most valuable asset: your life time. How much time do you want to invest in a financial system that will be dead quite soon anyway?
